Definitions

  • the present invention relates to acoustical panels used for attenuating noise and reverberations in provate and public rooms.
  • acoustical panels used for attenuating noise and reverberations in provate and public rooms.
  • sound-attenuating products are mainly produced as mats or padded panels.
  • the panels are often fully or partly cast in a sound-absorbing material or a surface material covering a sound-absorbing core.
  • acoustical panels, screen walls, partition walls and quiet rooms are constructed in this way.
  • the products have a relatively large surface area to absorb the sound. They are constructed as rigid
  • Document US4989688 discloses an acoustical wall panel comprising individual cells formed by a divider grid inside a peripheral frame . Each cell has solid, low density insulation material and the panel has front and rear covers which can be decorative. Document US4989688 discloses all the features of the preamble of claim 1.
  • metal truss products such as fences, walkways, protections, reinforcements, etc.
  • the invention is inspired by elements from these two different product segments.
  • pads of attenuating material e.g. felt
  • the panel may be made with a pictorial and patterned surface.
  • the filled-in openings in the truss may strongly resemble greatly enlarged openings in a carpet.
  • a carpet is soft and not self-supporting and has to be hung or laid against a surface.
  • the inventive sound-absorbing panel is rigid and self-supporting, with the design possibilities and advantages inherent from this.
  • Panels mounted together in a regularly repeated pattern could form larger surfaces.
  • the shape of the panels and/or their outline may vary from flat rectangular to 3-dimensional irregular design.
  • the supporting core of the panel - the truss - may be produced in several ways.
  • the most effective form of production will probably be as welded wire trusses corresponding to a stiff truss fence.
  • the truss may with advantage be produced according to a several standards with different opening sizes providing the panels with a spectre of sizes and designs.
  • the truss in the panels may be produced without a frame to hang on a wall, and with a frame to provide better rigidity and possibility of connetion of panels.
  • Other ways of producing the truss may be as expanded metal (rib mesh), punching, casting, water - or laster-cutting of plastic, metal or other suitable materials.
  • pads for filling the openings in the truss, or fastening thereto is mainly thought to be as punching or cutting of sound-absorbing felt, but other materials and methods of production may also be relevand.
  • Felt provides excellent sound attenuation but is relatively costly. Examples of other suitable materials may be leftovers from the textile industry, decor seam on the pads, light or colours, patterns in different materials, to provide a desired effect in relation to the product's surface and look.
  • the sound-absorbing pads may be designed in different ways in order to be fastened to the supporting truss.
  • Figures 1-3 show two different ways of fastening the pads to the truss.
  • Figures 1 and 2 show a standard metal truss 2 wherein felt pads 1 are forced through the openings 3 in the truss as pixels forming a larger picture surface.
  • Figure 1 shows the finished cut felt pad 1 at the left hand side and the felt pad 1 pressed through and fastened to one of the openings 3 in the truss 2 at the right hand side.
  • the felt pad 1 is designed with grooves acting as a locking arrangement 4 of the pad for fastening the pad 1 in the correct position in the openings 3 of the truss 2.
  • Figures 2 shows four ways of fastening felt pads 1 to the openings 3 in a standard metal truss 2, providing different structures and expressions in the surfaces which are formed when the different felt pads 1 are fastened to the openings 3.
  • Figure 3 shows larger pads 1 which are cut from felt mats. They are fastened to a standard truss 2 with two locking arrangements 4 which are threaded through the truss openings 3.
  • the locking arrangements 4 are equipped with hooks 5 and a section 6 which is cut in the front allowing the locking arrangements 4 to be easily bent backwards so that the pad 1 will hang down neatly on the front side.
  • not all the openings 3 in the truss 2 are used. This means that is may be appropriate to develop different formations of trusses 2 to different pads 1 dependent on which type of structure and expression one wishes to bring forth in the finished surface that is created when more pads 1 are fastened to the truss 2.
